I hesitate to chime in when users named FindingFreestyle and StrokeDoctor have commented extensively, but...
It would appear that your hand has too much side-to-side motion during your pull. I think the current view is that the hand should trace as straight a line (viewed from above and relative to the pool, not your body) as possible from hand entry (in front of the shoulder, not the head as you seem to do a bit) to hand exit. The old S-stroke is no longer.
I recall finding an overhead view of Sun Yang in some championship, and his hand draws a perfectly straight line. Any sideways motion is wasted effort. (edit: here's a good example. Check out slow motion at 1:30)
Your stroke looks good from that limited view. You might want to stop trying to avoid hurting the water on hand entry: pick up the recovery arm speed and get that hand back into the water!
